7 Application filed September 12, 1913. Serial No. 253,848.

To all whom it may concern: Be it known that we, CLEoN BINE RUSH and.JAMES JOSEPH ,MORGAN, subjects of the King of Great Britain and Ireland,residing in Wellington, New Zealand, have nvented a new and usefulImprovement 1n Tipping-Gears for Motor-Vehicles and the like; and we dohereby declare the following to be a. full, clear, and exact descriptionof the same This invention relates to an improved tipping gear for motorvehicles and the like.

According hereto the body of the wagon is made to slideback upon risersor sum mers and when at the end of its slide to tip on a suitable checkshaft. The check shaft is mounted in brackets attached to the body andis carried along to the tipping position in slots provided in thechassis risers.

The means whereby the body is made to slide back comprise a winch withfast and loose drums which are so arranged that the body may be hauledback to the tipping position by a winch rope or the like attached at oneend to one of the drums, the said rope passing over a fixed pulleypreferablysituated on the back of the chassis, the other end of the ropebeing fixed to the body. When the tipping is completed the body may behauled back to the horizontal position by means of a rope fixed at oneend to the body and at the other end to the second drum.

The check shaft above mentioned keeps the body in the correct position,but if desired suitable guide plates or other guiding device may bemounted upon the risers.

The sliding is facilitated by rollers suitably attached to the bodywhich run upon the risers above the chassis.

The winch is provided with a suitable clutch to enable the loose drum tobe made fast. A pawl or the like device is provided to keep theapparatus locked. The apparatus may be worked either by a hand lever asshown or by a mechanical drive from the engine.

One form of the invention is illustrated in the accompanying drawings,in which similar numerals of reference indicate the same partsthroughout. Q

Figure l, is a side elevation showing the position of the winch andropes, and; the various positions of the body while it is being tipped,

Fig. 2, shows a sectional view of a roller and ofthe check shaft. Fig.3, shows an elevation of Fig.2; Fig. 4, shows a plan of the winch. 1Fig. 5, is an elevation of Fig. 4.

Fig. 6, illustrates a resilient formof at tachment of the tipping chainto the body. In the drawings, the body 1, is mounted on risers orsummers 2, placed above the chassis Avplate 4, projects from the side ofthe body over? the uppermost of the risers 2, and upon the insidethereof Such plate 4, receives a'check shaft 5, provided with a suitablecollar 6 as indicated in Figs. 2 and 3. The checkshaft 5, runs in'theslot 7', of the plate 8, and extends across to the opposite andcorresponding riser which is similarly' constructed. When the body isslid back this check-shaft rollsand thus prevents undue friction in thesliding process. The check shaft 5, also tends to keep the body in thecorrect position, and 'it i's upon this check shaft 5, that'the body istipped.

The top of the chassis riser 2, is provided with a metal strip 9, uponwhich runthe rollers 10, mounted under the body risers 11, in a suitablemanner.

The winch, as shown in Figs. 4 and 5is suitably mounted in the positionindicated in Flg. 1. Such winch consists of three drums 12, 13 and 14,mounted on a common axle 15, which may be made to rotate'by means ofcranks 16, and a shaft 17 and gear wheels 18, and 19. The drum 14 is notkeyed to the shaft 15, but may be attached to it by a suitable clutch20, operated by the crank 21. The rope 22, connects the drum 13, withthe body at 23. The, rope 24, connects the drum 14, with the body at 23,and is passed over a sheave 25, suitably mounted at the rear of thechassis. The

chain 26, connects the drum 12, with the body at 27, and is passed overthe sheave 28, suitably placed at the. rear of the chassis. The winchshaft 15, is provided with a ratchet wheel 29, with which a pawl 30, maybe made to engage.

The attachment of the tipping chain 26, to the body at 27 ispreferablyinade resiliint, and one form of attachment is shown in ig.v6. v

The operation of the device is as follows:

When. the body 1, is in its normal position, as shown in full llnes inFig. 1, the chain 26, is slack, theclutch 20, is engaged with the drum'14, the rope 22, on the 'fast drum 13, is fully wound and the rope 24,on the loose I drum 14, is paid =out 'e. spent). In commencing thesliding operation preparatory to tipping, the lpawl 30,is*released. Theclutch is engaged and the winch is set in operation in such-a way as'tocause the rope I 24:, to wind up on to the drum 14, whereby at the sametime the 'rope'22, is unwound. Consequently the point 23, (i. e. thepoint of attachmentof these ropes to "the body), and thereby the bodyitself, move toward the tipping position'as shown indottedlines 31, Fig.-1. The enact is now disengaged whereby the 'rope 24, on the loose drum'14, is released and the-tipping iscompleted by continuing to Work thewinch in the same manner as-before, whereby the chain 26, will be woundup thereby insuring'the completion of the tipping, as shown in dottedlines 32, irrespective of "the distribution of the load in the body.

To'return thebod-yto its normal-position, the winch is wound in thereverse direction whereby the rope is WOlll'lCl onto the fast drum 18and the chain :paid out, the clutch being disengaged duringthis process.

When the winding is=completed and the body is returned *to the-ordinaryhorizontal position, as shown in full lines-in Fig. 1,-the

clutch 20 is put in and the pawl 30 is brought into engagement with theratchet wheel 29 and the apparatus is thereby locked.

What we claim is I In a tipping wagon, a body adapted to slide, a ropewinch whereby the bodymay be made to slide to tipping position and berecovered therefrom, rollers on said body, risers on'which said rollersare adapted to roll, said risers being formed with substalr tiallyhorizontal slots, plates secured to the body and adjacent said risers, acheck shaft mounted in said plates and fitting'in said slots, said winchcomprising three drums, one of said drums loose on its shaft, a clutchto lock said loose drum to its shaft, and avflexible member attached" toeach of said drums, one of which members is adapted to tilt said body,the other members adapted to impart forward and rearward motion tosa'idbody.

In-testimony whereof, we have signedour names to this specification inthe presence oftwo subscribing witnesses.
